Stars have fascinated humans since the beginning of time. They are the glittering lights that decorate the night sky and inspire us to dream beyond our mundane existence. Every culture on earth has assigned different meanings to the stars, viewing them as symbols of guidance, hope, and magic.

What is a Star?

A star is a massive, luminous sphere of plasma held together by its own gravity. It emits energy, light, and heat through fusion reactions that occur at its core. Stars are born from vast clouds of gas and dust, and they can live for billions of years, undergoing various stages of evolution before dying.

The Different Types of Stars

Stars come in different colors, sizes, and temperatures. Their classification depends on their surface temperature or spectral class, measured in Kelvin. The most common types are:

O – Blue stars with surface temperatures above 33,000 Kelvin
B – Blue/white stars with surface temperatures between 10,000 and 33,000 Kelvin
A – White stars with surface temperatures between 7,500 and 10,000 Kelvin
F – Yellow/white stars with surface temperatures between 6,000 and 7,500 Kelvin
G – Yellow stars with surface temperatures between 5,250 and 6,000 Kelvin (Our Sun is a G-type star)
K – Orange stars with surface temperatures between 3,500 and 5,250 Kelvin
M – Red stars with surface temperatures below 3,500 Kelvin

Interesting Facts about Stars

Stars are full of surprises. Here are some fascinating facts about them:
